Poor Pete — Ashlee crushed him. Sources say that ‘he does NOT want it to be over!’

Pete Wentz was left completely heartbroken when his wife Ashlee Simpsonfiled for divorce on Feb. 9 in Los Angeles, Calif. “Pete has been crying a lot to her about this,” a source close to the couple tells RadarOnline.com. “He is crushed, and does not want it to be over.”

On Feb. 10, TMZ reported that Pete, 31, begged Ashlee, 26, not to go through with it, but to no avail. “Ashlee is done,” explains the source. “She loves him, but she’s ready to move on.”

“When he traveled for work, she had a lot of time to think and in the end she just felt happier without him,” adds the source. “They married really young and have grown apart, she just wants to focus on her child and her career.”

According to the source, Pete had no clue that this was coming. He was even planning a Valentine’s day surprise for Ashlee.

Pete was also spotted stopping by Ashlee’s parents’ house in L.A. on Feb. 10. Could he have been seeking advice from papa Joe Simpson on how to win Ashlee back?

Friends of Ashlee blame the split on Pete’s “erratic behavior,” while Pete’s people are saying that the couple just grew apart.

Pete and Ashlee married in May 2008 and have a 2-year-old son, Bronx, together. Ashlee is asking for joint legal custody and primary physical custody of the tot.
